The fort, now closed to the public and only the surrounding park can be visited, was built between 1909 and 1912. It belongs to the series of fortifications that were defined at that time as the “last generation”, made of reinforced concrete. The fort consists of a single defensive block, made in two levels. It has a capacity to accommodate 90 artillerists and 50 infantrymen. Before World War I, it was equipped with guns in a revolving dome and some machine guns for close defence. Due to its being remote from the front line and obsolete in view of modern combat techniques, the fort had lost its function by the year 1916. The armaments were transferred to the front line and the park was used as a war vegetable garden to supply food for the army.
